  1. 1. 2D Reflection Seismic Imaging of Rødby Structures, Denmark: Geological Conditions for CO2 Sequestration

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Mussie Habtemariam Zeru; [2024]
    Nyckelord :Reflection seismic; Geologic carbon storage; Sandstone; Structures; Rødby;

    Sammanfattning : Amidst the global climate action movement, geologic carbon storage (GCS) has emerged as a pivotal strategy for mitigating atmospheric CO2 levels, offering environmental and economic opportunities. This thesis targets the Bunter Sandstone Formation within the Rødby structures in Denmark, focusing on seismic Profile 1.

  3. 2. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Felicia Hagberg; [2024]
    Nyckelord :PFAS; PFCA; PFSA; stormwater; guidelines; foam fractionation; activated carbon; anion exchangers; PFAS; PFCA; PFSA; dagvatten; riktvärden; åtgärder; skumfraktionering; aktivt kol; jonbytare;

    Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

  4. 3. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  5. 4. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Maja Holm; [2024]
    Nyckelord :Physical geography; ecosystem science; soil organic carbon; soil sampling; perennial crops; carbon sequestration; carbon farming; Kernza™; soil organic carbon stock; Earth and Environmental Sciences;

    Sammanfattning : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. LÄS MER

  7. 5. Quantification of Pharmaceuticals at the sub-cellular level using the NanoSIMS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk kemi

    Sammanfattning : Mass spectroscopy imaging (MSI) has become a vital tool in modern research due to its ability to visualize the spatial distribution of molecules within tissue samples. The collaboration between researchers at AZ, the University of Gothenburg, and Chalmers University of Technology using the NanoSIMS instrument and MSI-SIMS technology has opened up new avenues of exploration in pharmaceutical development, particularly in examining drugs and metabolites at sub-cellular levels.
